Looking at the syllabus and past papers you would certainly decide that you should go for it as you would have studied almost every single topic of physics. During engineering studies, one reads it in different segments and on yearly basis while here in CSS exam you have to cover it all in once, it is LENGTHY. And that makes it a bit hard nut to crack simply because you will loose the spirit in between.

If you think you can keep the interest going only then opt it otherwise there are many wise choices...and engineers fit in everywhere

Also read it here.
